Butch, while you are somewhat correct in the pin assignments, polarity does not matter on a T1 circuit. The only thing that matters is proper placement of the transmit and receive pairs. As long as pins 1,2,4 and 5 are used, that is all that is required.
"A 568B plug is wired T-R-T-R-T-R-T-R. "
Well, sort of on 568B:
Tip 1 is jack position 5
Ring 1 is jack position 4
Tip 2 is jack position 1
Ring 2 is jack position 2
Tip 3 is jack position 3
Ring 3 is jack position 6
Tip 4 is jack position 7
Ring 4 is jack position 8
Yea, I agree that this issue has likely been resolved by now, but it is important to keep even responses to old threads accurate.
